floppy gearlinkage (not the usual bush)

[nick9one1]

Hi,

Right my first project with the new car is the 'floppy' gear linkage. Front to back is pretty good but left to right its very loose.

I don't think its the usual worn bearing on this part http://www.design911.co.uk/fu/prod7325/Gearshift-Lever-Porsche-924---924S---944/ (although I will order one anyway).

It seems to be loose much further down the transmission tunnel. Is it common for another area back there to work loose?

Hopefully this video might describe it much better than I can!

Hi Nick
The gear lever you've ordered will make a big difference but there is also the linkage at the other end with a plastic cross piece which wears - cost is approx £100

Perfect, So I need to get hold of Part 18 (944 424 013 02).

I guess this is Porsche only and bet they don't do mail order!

Yes it is a Porsche only part and Yes any Porsche dealership will order and send the part to you. Always check the price of the part from Porsche before you buyer from another seller as usually you will find the prices Porsche charge for parts surprisingly cheaper.

Try Jon Mitchell as I think that they have had the cross over the part remade.

My OPC do post stuff out to me, I got the Gear lever and the cup bearing it sits in sent to my home for £39 all-in

Just out of curiosity, would a short shift kit as described here replace the part I need?

Yes is the quick answer.
Can be fiddly to do while box is still on the car as you can't see very well.

 

[nick9one1]

excellent, ive ordered one from the states, came to about £60 inc p&p.
Certainly cheaper than £108 porsche were asking for the OE part.

The reason I asked about the bush is John Mitchell can supply the nylon bush only, although he's yet to come back to me with a price.

No you need part 21. It includes couple of rubber washers and the plastic cross piece.

 

[nick9one1]

doesn't the replacement short shift replace that part?

I finally managed to replace the linkage! Needed to use a ball joint splitter to pull part 18 from the shaft coming out the side of the gearbox. Things have improved, much less throw, but still a lot of side to side slop!!

Now I'm really scratching my head.

It will be your gearlever joint where the actuating rod comes out. You will need to drill out and bush the operating arm as there will still be wear in it. By the way, a new gearlever is £25 from OPC.

Nick,

In addition to Alastair's comment (which I guess from your other post that you are already on to sorting), did you check for play between parts 29 and 28?

The articulated shaft (# 29) has plastic bushes in either end similar to a windscreen wiper mechanism. I've seen these wear a fair bit.
Part # 944 424 141 00 ~ £8 from Porsche.

For reference, the top of my gear lever moves by < 10mm side to side before I can feel the selector rod spring.

 

[nick9one1]

Thanks for the suggestions..


there Isnt any play in the front gearlever, as when I move it left-right I can see the long rod (part 14) moving, indicating the play is at the gearbox end.

After a quick look last night I couldn't see any play in the new short shift I installed, or part 29.

Its as if the play is occurring somewhere between the front of part 14 and the rear. Which is impossible as its a solid rod!!

I will investigate some more tonight...

 

[sulzeruk]

Unless you have bushed the long rod, there will be play there. 0.5mm equates to a lot of movement at the end.

Needed to use a ball joint splitter to pull part 19 from the shaft coming out the side of the gearbox.

Reading your earlier posts again; I'm confused by your above comment.

From memory, part 19 is an M7 or M8 bolt with a pointed end, which when torqued-up locates in a dimple in the linkage rod and holds it square to the long rod... This, combined with a reasonably close fit, should mean no relative movement between the linkage rod and the long rod. Worth a look?

How much side-to-side movement do you have?

Sorry I meant part 18!
I removed the bolt (in red) and had trouble pulling the arm off the shaft due to corrosion (yellow arrow). That's where i needed to use a balljoint splitter.

You could be right, if that bolt was loose I would have movement.... just going to check!

 

[nick9one1]

not that clear but gives you an idea..

Like you say - not that clear. It has to be something significant to give you so much movement.

To my eyes, there appeared to be some relative movement in the acticulating arm connection (~35 seconds) and the central linkage pivot (~55 seconds).

I realise access is very limited but I would check all the connections above the gearbox, whilst someone is waggling the gear lever. Or perhaps take a video from directly above showing all the linkages.
